PTAB challenges

As a senior PTAB practitioner analyzing US Patent 9,107,000, here is my assessment of its post-grant challenge history for a defendant.

Proceedings overview

There has been one AIA trial proceeding filed against US Patent 9,107,000. That single inter partes review (IPR) is currently active, with the Patent Trial and Appeal Board (PTAB) having instituted a trial on the challenged claims. This indicates the patent is vulnerable to the invalidity arguments raised, giving a defendant a favorable defensive posture pending the outcome of the trial.

IPR2025-01541 — Samsung Electronics Co., Ltd. et al. v. ONE-E-WAY Inc

• Type: Inter Partes Review
• Filed: 2025-09-17
• Status: Trial Instituted. This means the PTAB determined that the petitioner, Samsung, established a reasonable likelihood that it would prevail in showing at least one of the challenged claims is unpatentable. The trial is now in progress.
• Judge panel: I am unable to confirm the specific judge panel from the available search results. This information is typically found on the first page of the Institution Decision.
• Petition grounds: I cannot definitively state the exact claims and prior art grounds from the search results. This information is detailed in the IPR petition and the subsequent Institution Decision, which would need to be retrieved directly from the USPTO's PTAB E2E portal. The grounds would be for anticipation (§ 102) or obviousness (§ 103) based on prior art patents and printed publications.
• Institution decision: The trial was instituted on or around 2026-03-17. The panel found Samsung's petition met the statutory threshold for instituting an IPR, indicating the invalidity arguments were persuasive enough to warrant a full trial.
• Final Written Decision: Not yet issued. The statutory deadline for the PTAB to issue a Final Written Decision (FWD) is one year from the date of institution, making the expected deadline approximately 2027-03-17.
• Settlement / termination: None. The proceeding is active.
• Appeal: None. A final decision has not been rendered.
• Defensive value: The institution of this IPR is a significant positive development for any defendant. It confirms that the PTAB, composed of expert administrative patent judges, sees merit in the invalidity challenges. A defendant should monitor this proceeding closely, as a final decision canceling the asserted claims would likely resolve its own litigation favorably.

Strategic summary

The patent owner, ONE-E-WAY Inc., is actively asserting this patent family in district court litigation against major technology companies, including Samsung. Samsung's response included filing IPR2025-01541, a common defensive strategy to challenge patent validity in a specialized and often faster forum than district court.

Currently, all claims of US Patent 9,107,000 are formally valid but are now under the cloud of the pending IPR. The claims for which trial has been instituted are at significant risk of being CANCELED. No claims have been finally sustained or tested by the PTAB.

For a defendant unrelated to Samsung, the estoppel landscape is clear. Since no final decision has been issued, no § 315(e)(2) estoppel has attached. A new defendant is free to file its own IPR petitions based on any prior art grounds it develops, including art that was not used in Samsung's petition. Once the FWD in Samsung's case issues, Samsung and its real parties-in-interest will be estopped from raising any invalidity ground in another forum that they raised or reasonably could have raised in the IPR.

Recommended next steps

A defendant facing a demand letter citing US Patent 9,107,000 has a clear path forward:

1. Monitor the Active IPR: The most crucial next step is to closely follow the developments in IPR2025-01541. Key upcoming milestones include the Patent Owner's Response, the oral hearing before the PTAB panel, and the Final Written Decision, which is due around 2027-03-17.

2. Obtain Key Documents: A defendant should immediately download the Petition and the Decision on Institution from the USPTO's PTAB End-to-End (E2E) portal for IPR2025-01541. These documents will provide the specific claims challenged, the prior art references used, and the detailed reasoning for why the PTAB decided to institute the trial. This information is invaluable for assessing the strength of the invalidity case.

3. Evaluate a Stay: Given the instituted IPR, a defendant in district court litigation should strongly consider filing a motion to stay the court case pending the PTAB's final decision. Courts frequently grant such stays to promote efficiency and avoid duplicate efforts, especially when the PTAB has already found a likelihood of invalidity.
